itachi died and he got the powers transferred to him
yes
no sasuke can't
mangekyou sharingan
Itachi, that's if you're referring to how Sasuke achieved the Mangekyou Sharingan. When Madara reveals that Itachi was doing things for the better of Sasuke's life, Sasuke realizes that Itachi was the closest person to him which activates the Mangekyou Sharingan.
i think sasuke will give naruto itachi's mangekyou sharing makin(sage mangekyou fox mode) then it will be madara vs sasuke and naruto
*I'll only answer about Sasuke's Mangekyou Sharingan Sasuke can perform an early stage of Susano'o, he can do the Ameterasu (the Eternal Black Flames), and Tsukiyomi (powerful Uchiha Genjutsu). Sasuke will get the Eternal Mangekyou in the manga, but how it will look like and what Sasuke will be able to do is unknown
Sorry for being a Spelling Nazi but it is spelled Mangekyou Sharingan. Yes Uchiha Sasuke can use Mangekyou Sharingan. He gains it after defeating Itachi in Shippuden.
he got the mangekyou once he defeated itachi.
so far we've seen his mangekyou preform Amaterasu
Sasuke Uchiha learned to use the three tomoe Sharingan in Part I of the Naruto series, and later unlocked the Mangekyou Sharingan after Itachi Uchiha's death. Through further development and training, Sasuke eventually awakened the Eternal Mangekyou Sharingan.
Is one like a star of 6 poits.
He gains Mangekyou Sharingan by killing his brother Itachi.
